x86: unification of i386 and x86_64 Kconfig.debug
Adding proper dependencies so the two Kconfig.debug files are now identical and move the result file to x86. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

- help
- Write kernel log output directly into the VGA buffer or to a serial
- port.
-
- This is useful for kernel debugging when your machine crashes very
- early before the console code is initialized. For normal operation
- it is not recommended because it looks ugly and doesn't cooperate
- with klogd/syslogd or the X server. You should normally N here,
- unless you want to debug such a crash.

-config DEBUG_STACKOVERFLOW
- bool "Check for stack overflows"
- depends on DEBUG_KERNEL
- help
- This option will cause messages to be printed if free stack space
- drops below a certain limit.
-
-config DEBUG_STACK_USAGE
- bool "Stack utilization instrumentation"
- depends on DEBUG_KERNEL
- help
- Enables the display of the minimum amount of free stack which each
- task has ever had available in the sysrq-T and sysrq-P debug output.
-
- This option will slow down process creation somewhat.

-config DEBUG_PAGEALLOC
- bool "Debug page memory allocations"
- depends on DEBUG_KERNEL && !HIBERNATION && !HUGETLBFS
- help
- Unmap pages from the kernel linear mapping after free_pages().
- This results in a large slowdown, but helps to find certain types
- of memory corruptions.
-
-config DEBUG_RODATA
- bool "Write protect kernel read-only data structures"
- depends on DEBUG_KERNEL
- help
- Mark the kernel read-only data as write-protected in the pagetables,
- in order to catch accidental (and incorrect) writes to such const
- data. This option may have a slight performance impact because a
- portion of the kernel code won't be covered by a 2MB TLB anymore.
- If in doubt, say "N".
-
-config 4KSTACKS
- bool "Use 4Kb for kernel stacks instead of 8Kb"
- depends on DEBUG_KERNEL
- help
- If you say Y here the kernel will use a 4Kb stacksize for the
- kernel stack attached to each process/thread. This facilitates
- running more threads on a system and also reduces the pressure
- on the VM subsystem for higher order allocations. This option
- will also use IRQ stacks to compensate for the reduced stackspace.

- bool "Enable doublefault exception handler" if EMBEDDED
- help
- This option allows trapping of rare doublefault exceptions that
- would otherwise cause a system to silently reboot. Disabling this
- option saves about 4k and might cause you much additional grey
- hair.
